TRUSS.

SPECIFICATEN forming part of Letters Patent No. 318,434, dated May 19, 1885.

Application ined september 13, 1894. (No mael.)

To all zal/"1,0111, it may concern.-

Be it known that I, ALFRED PULLAR, of Edinburgh, in the county of Mid-Lothian, Scotland, have invented an Improvement in Surgical Trusses, of which the following is a specification.

Theinvention relates to an improvementin surgical trusses, and has for its object the protection of every portion of such trusses from the perspiration exuded or the moisture emitted from the human body,and also from water during bathing.

The invention consists of a sheath of vulcanized caoutchouc, or of other suitable flexible material, of such a shape as to adapt it to cover the entire metallic portion of the band, as also the pad of the truss, as will be described with reference to the accompanying drawings, in which- Figure l is a face view of the softrubber casing or sheath. Fig. 2 is a transverse seetion thereof on the line A B, looking in the direction ofthe arrow. Fig. Sis an elevation ot' a truss with my improved sheath applied.

a represents the sheath which is slipped over the pad and belt of the truss, so as to eX- elude all moisture from Contact therewith. This sheath is provided at the enlarged portion c, which is adapted to inclose the pad of the truss, with an eye for the passage of the stud or button b,which projects from said pad, and over which the button-holes in the strap d for securing the truss to the wearer are adapted to loe slipped. To prevent tearing, this eye is re-enforced or the material doubled, as shown atf; and in order to cover that portion of the pad which would be exposed through said eye I employ a hat rubber plate or washer, e,which is punctured and slipped over the stud b, its edges underlying those of the eye, as shown by dotted lines in Fig. l. This is important, as without the use of such a plate or washer water would be admitted through the eye and be absorbed by the pad or find its way to the inside of the sheath,and thereby damage the truss.

The re-enforcef is not only beneficial as such, but also serves to exclude the water from the interior of the sheath by bearing firmly against the face of the pad.

The open end of the sheath ct is contracted, and also reenforced, as represented atf, in order to prevent the admission of water at this point.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with the belt and pad of a truss, of a ieXible sheath for completely inclosing them, open at one end and having an eye for the passage of a stud projecting from the back ofthe truss, as and for the purpose set forth.

2. In combination, a truss having a band or belt, a pad, and a stud, b, projecting therefrom, a sheath, a, open at one end, having an enlargement, c, at the other, and an eye for the passage of the stud b, and a rubber washer, e, surrounding said stud, as and for the purpose set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED PULLAR.
